At the site at http://www.geocities.com/CollegePark/Quad/3034/ there is a representation of a flag for Balochistan. As many of the links on that site seem spurious, there is some doubt as to the existence or authenticity of this flag.

The flag internationally recognized is at
this site
where you can get a link and all the meanings of the flag and information
about it.. The old flags are no longer used. The flag with light sky blue,
white star and green over red is the international flag of Baluchistan,
including the Baluch people of Baluchistan, Iran, Balochistan, Pakistan,
Baluchistan, Afghanistan, and Baluchistan, Turkmenistan. The flag was
invented on 27 January 1982 by the Baloch United Movement which is now the
government of Baluchistan. Adaar, Baloch, 16 September 2001

The flag can be seen in use in the following videos:

Red is the sign of moral heroism for those who suffered martyrdom. Green

marine and celestial frontiers. The white star is the sign of the moral
heroism, manliness and generosity.Adaar, Baloch, 16 September 2001

National Flag of Baluchistan
The aim of this document is to introduce in brief the history of the current
National Flag of the greater Baluchland and to help those who
use the Baluch national flag to reproduce it correctly. The document contains
the basic rules for the construction of the flag as well as
the standard colors to be used and known.

HISTORICAL BACKGROUND: The National Flag was first introduced by the leaders of
the Western Baluchland in 1960, in Egypt, Romania and later in Iraq for the
National Front for the Liberation of Western Baluchland to represent the Baluch
Nation in their struggle for independence and free Baluchland from the illegal
domination, oppression and occupation of the Persian tyrant kings. It was
subsequently presented to the members of the international delegation at the
peace conferences that devised a plan for Baluch Nation independence. Under the
same flag the Baluch leaders announced the formation of the first "Baluchi
Government in Exile" in 1961 in Egypt and fought a drawn-out war until 1972, in
order to revive the Baluch Nation national independence, lost since 1415.

Flag of Baluchistan 1965
In 1961 and the creation of the Government of Baluchland, the old "Chakari flag"
which was red with the picture of a black panther, the new one was adopted by
its parliament as the official Flag of the government of Baluchland in the
country and abroad. Following these historic background, the National Flag is
widely adopted in Greater Baluchland anonymously and has been set aloft by
various Baluchi political parties and entities in all sectors of the Baluchland
and abroad. The Flag of grater Baluchland has thus been consecrated by the blood
of all Baluch martyrs patriots of this century, from tens of thousands who fell
in defending the independence movement under the new government and leadership.

The flag was aloft when Nasir was immolated in 1960; it was aloft when wounded
Baluch on stretchers were placed before the firing squads under cruel Iranian
Shah rules; it was aloft when Baluch civilians were gassed in their hundreds in
villages in Aahurran and Zardkouh in Baluchland; it was aloft when hundreds of
Baluch innocent were driven from their villages and towns that have been set
alight since 1958-59; and, it remains aloft everywhere today—more than 5 decades
after the loss of Baluchland independence--when Baluch are redoubling their
perennial struggle to regain their dignity and equality with other nations by
reviving their right to choose the course of their own future.

DESCRIPTION OF THE NATIONAL FLAG:
The National Flag of Greater Baluchland consists of a tricolor field, with a
five dimension star in the blue field.

TRICOLOR FIELD: The Baluch National flag has two horizontal bands. The upper
stripe is green, the first one sky blue with a white five dimension star and the
bottom band is red. The width of the flag is two-thirds of the length.

NATIONAL FIVE DIMENSION STAR: The primary Baluch characteristic of the flag is
the white five dimension star at the beginning. The 5 dimension of the star is
the Baluchi Standard Language, secularism, cultural, the heroic history among
the Baluch, stretching into antiquity. The five angle star disk has many
decades' olds; every angle is equal in size and shape. The number angles hold a
primary importance in the native Baluch heroic secularism and cultural tradition
of the Baluch Nation.

Using the given flag dimensions of 2:3, the star disk has a diameter of 1.0
including the rays and 0.5 without them. These rays have straight sides, come to
a sharp point at their outer end, and form an inverse point where they meet each
other and the central disk. The star appears in the exact center of the sky blue
of the flag. The star is placed so that the flag's vertical meridian passes
through its topmost point as described above.

GREEN sign is the blossomed spring of our freedom.
SKY BLUE sign is the might of our marine and celestial frontiers.
WHITE START sign is our moral heroism, manliness and generosity

The variant presented by Eugene Ipavec, with the 24-rays sun, although well
documented by a photo of it being actually waved (in London) is nowhere to be
seen elsewhere. In 2005, the Balochistan Peoples Party-BPP- was admitted to UNPO
with the flag of 12-rayed sun. BPP represents only the West Balochistan (the
Iranian part in Sistan-wa-Balochistan Province) and, at the time of admission to
UNPO, called on their eastern brothers (in Pakistan) to follow their move and
join UNPO too. UNPO lists West Balochistan as a member, with the flag (12 rays)
It also lists Balochistan as a member, but without the flag. Then, in 2006, the
Government-in-Exile of Balochistan was formed in Jerusalem, Israel, presumably
claiming to represent all parts of Balochistan (Pakistan, Iran and Afghanistan)
with the declared capital in Kalat (Pakistani Balochistan) and the present
holder of the title of Mir of Kalat, Suleman Dawood Khan (transcription of his
name varies widely) as the King of Balochistan. That government uses the same
flag as BPP, and describes it on its website as follow:
"Green: its the color of prosperity - the dry barren land of Balochistan turns
green after rainfall as small plants sprout. Liberty is like rainfall, and when
achieved, it will sprout the Baloch nation into prosperity.
Red: it is the color of blood, hardiness and valor - the Baloch martyrs proudly
sacrificed their life and shed their blood on the soil of Balochistan for
liberty.
Blue: it is the color of ocean and sky, and it signifies vigilance, perseverance
and justice - the Baloch will continue their struggle until freedom is achieves
and justice is served.
White: it is the color of peace, purity and innocence - the Baloch people want
to live in peace and harmony as a free nation.
Rising Sun: it is a sign of a new beginning - the Baloch nation begins a new day
as a free nation. Chrystian Kretowicz, 25 April 2008

The flag of the Governor of the Province of Balochistan, Pakistan, is dark
green with a central yellow disk bearing a scene of a large building with green
branches on the sides, a white star and crescent moon above, and Urdu text
beneath.

This is a flag researched by Juanjo Gonzalez that was used for a revolutionary movement some years ago, but he is not sure if it is currently used.Jaume Ollé, 16 September 1996

This flag (white with upside down red star) is used by Baloutche Warna (Baluch Warriors Organization) led by Sirdar Akbar Khan Bugt. The flag is shown in the
Flags of Aspirant Peoples chart. Two other flags are reported from no vexillological sources:
the same flag with a green stripe in the lower part (the green is attributed
to joining with the Islamic liberation struggle) and the same flag as the first one but with a green star instead red. It may be a variant of the first one or a mistake, or perhaps is used by a split-off of the Baloutche Warna. Jaume Ollé, 1 February 1999

"In 1997, a faction within the BNP, led by Israrullah Zehri changed its
loyalties and formed Balochistan National Party (Awami). Akhtar Mengal accused
the Federal Government of bribing the renegade members of the party to do so.
But the final straw happened to be the testing of Pakistan's nuclear weapons on
Ras Koh in Chaghi without taking the Provincial Government into confidence
first. Due to all this tension, especially BNP's protest on the Nuclear Tests,
the Akhtar Mengal-led government was dismissed and with the help of Israrullh
Zehri's Balochistan National Party (Awami), a new government was formed in
Balochistan."

"Sardar
Attahullah Mengal is Chief of BNP and Party has popular support in Balochistan
province. Sardar Attahullah was first elected Chief Minister of Balochistan
province in 1972, but soon after pro-people reforms and ideas, Punjabi dominated
Pakistan military overthrow Mengal Government and sent troops to eliminate
political leaders and get control of Balochistan resources.

Sardar Mengal
along with Nawab Marri and political leaders of Balochistan sent to Jail. After
spending four years in Jail Mr Mengal went to exile and returned in 1996 and
again revived the Party which sweep the 1997 election in Balochistan province
despite Pakistan military and intelligence agencies opposition, his son Akhter
Mengal sworn in as Chief minister of Balochistan province.

On 28th May
1998, Pakistan military tested its nuclear bomb in Balochistan without taking in
to confidence to Balochistan government and BNP who opposed the test on Baloch
soil. After one month of nuclear test and opposition, Pakistan intelligence
agencies succeeded to create rift and differences with in Party and Syed Eshan
Shah and Israrullah Zehri members/ ministers of BNP was paid Rupees 80 Million
by agencies to change the loyalty of members of provincial assembly. After
creating division and rift federal government installed new pro-Punjabi regime
in Balochistan in August 1998. In 2002 election BNP members have been bared to
take part in election freely, which allowed pro-military religious alliance MMA
to win all moderate and nationalist constituencies in Balochistan. After the
cold blooded murder of Baloch Nationalist Leader Shaeed Nawab Akber Khan Bugti
on 26 August 2006; BNP resigned in protest with it two members in National
parliament and two in provincial including all the local bodies elected members.
Balochistan National Party boycotted the general elections of 18 Febuary 2008.
Sardar Akhter Mengal is president and party has central cabinet and central
committee comprised on 44 members from all over Balochistan.

BNP believes
in secular, and nationalist ideas and party struggle is focused on
politico-economic autonomy for Balochistan. Party also believes on Non-Nuclearization
and De-Militarization of Balochistan region which is presently testing and
nuclear developing site of Pakistan military."
